PyQt5 – 为复选框中的复选指标设置背景图片

在这篇文章中,我们将看到如何为复选框的指标设置背景图片。在默认情况下,指标没有设置背景图片。为了将背景图像设置为仅用于检查状态的指标,我们必须改变检查状态的指标的样式表。下面是样式表的代码。

QCheckBox::indicator:checked
{
background-image : url(image.png);
}

以下是实施情况。

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
 
 
class Window(QMainWindow):
 
    def __init__(self):
        super().__init__()
 
        # setting title
        self.setWindowTitle("Python ")
 
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
    # method for widgets
    def UiComponents(self):
        # creating the check-box
        checkbox = QCheckBox('Geek ?', self)
 
        # setting geometry of check box
        checkbox.setGeometry(200, 150, 100, 60)
 
        # changing size of indicator
        # adding background image to the indicator
        # when it is in checked state
        checkbox.setStyleSheet("QCheckBox::indicator"
                               "{"
                               "width : 60px;"
                               "height : 60px;"
                               "}"
                               "QCheckBox::indicator:checked"
                               "{"
                               "background-image : url(indicator_image.png);"
                               "}")
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
